236-1 Fig.1 Schematic drawing of the apparatus for X-ray diffraction experiment. (A) Specimen was placed between two parallel discs, one of which was rotated with a constant rate (0-5 s) Through a chamber window made of Kapton film, X-ray beam was introduced through the specimen suspension and diffraction signals from aligned filaments were recorded with a Hamamatsu cooled CCD camera (camera le...

The Powder Diffraction File TM (PDF) is a comprehensive materials database that is the key source of reference powder diffraction data for identification and analysis of materials; from natural minerals and high-tech ceramics, to metals and alloys, and pharmaceuticals. New developments in X-ray analysis, and advances in scientific research, have dramatically influenced the range of data present...

limn2o4 spinel cathode materials have been successfully synthesized by solid-state reaction. surface of these particles were modified by nanostructured lifepo4 via sol gel dip coating method. synthesized products were characterized by thermally analyzed by thermogravimetric and differential thermal analysis(tg/dta), x-ray diffraction (xrd), scanning electron microscopy (sem), and energy dispers...

the catalytic oxidation of toluene over copper oxide supported on natural diatomite was investigated. the catalyst was prepared by the wet impregnation method and characterized by using the brunauer emmett teller (bet), field emission scanning electron microscopy (fesem), x-ray diffraction (xrd), x-ray fluorescence (xrf) and temperature-programmed reduction (tpr) analysis. the highest catalytic ...

in current work, cds/black carbon nanocomposites were successfully synthesized with the aid of chestnut and cadmium nitrate as the starting reagents. besides, the effects of preparation parameters such as reaction time, and precursor concentration on the morphology of products and removal of heavy metals (hg+2, pb+2) were studied by scanning electron microscopy images and batch adsorption mode....
